API Audit Logging
=================

Audit middleware supports delivery of CADF audit events via Oslo messaging
notifier capability. Based on `notification_driver` configuration, audit events
can be routed to messaging infrastructure (notification_driver = messagingv2)
or can be routed to a log file (`[oslo_messaging_notifications]/driver = log`).

Audit middleware creates two events per REST API interaction. First event has
information extracted from request data and the second one has request outcome
(response).

Enabling API Audit Logging
==========================

Audit middleware is available as part of `keystonemiddleware` (>= 1.6) library.
For information regarding how audit middleware functions refer
:keystonemiddleware-doc:`here <audit.html>`.

Auditing can be enabled for the Bare Metal service by making the following changes
to ``/etc/ironic/ironic.conf``.

#. To enable audit logging of API requests::

    [audit]
    ...
    enabled=true

#. To customize auditing API requests, the audit middleware requires the audit_map_file setting
   to be defined. Update the value of configuration setting 'audit_map_file' to set its
   location. Audit map file configuration options for the Bare Metal service are included
   in the etc/ironic/ironic_api_audit_map.conf.sample file. To understand CADF format
   specified in ironic_api_audit_map.conf file refer to `CADF Format.
   <http://www.dmtf.org/sites/default/files/standards/documents/DSP2038_1.0.0.pdf>`_::

    [audit]
    ...
    audit_map_file=/etc/ironic/api_audit_map.conf

#. Comma separated list of Ironic REST API HTTP methods to be ignored during audit.
   It is used only when API audit is enabled. For example::

    [audit]
    ...
    ignore_req_list=GET,POST

Sample Audit Event

Following is the sample of audit event for ironic node list request.
